Left: Tracing the superior longitudinal fasciculus (red) around a tumor (yellow) using functional landmarks (blue). Bottom two images show that tracing is much less successful when based on anatomical landmarks. Right: Quantitative measurements show that the displaced tract has elevated FA. This probably reflects increased packing density with tract compression, as there is decreased diffusion perpendicular to the tract, and increased diffusion along it (from ref. 29).
